The Fujifilm XF 18mm F1.4 is a great option for a bright, fast walkaround prime for X-mount shooters. Equivalent to 27mm F2.1 on a full-frame camera, it's fast enough to offer a decent separation between foreground and background, despite its wide field-of-view. Optically it's sharp wide open, offers pleasing bokeh, and has minimal chromatic aberrations. Autofocus is fast thanks to the use of linear motors, though video shooters may find the manual focus experience limiting. For X-mount shooters, the XF 18mm F1.4 is worth the price premium over the XF 18mm F2.
